MooER-MTL-5K

MooER (摩耳): an LLM-based Speech Recognition and Translation Model from Moore Threads

Online Demo: https://mooer-speech.mthreads.com:10077/

🔥 Update

We release a new model MooER-80K-v2 using 80K hours of data. Click here to try the new model.

📖 Introduction

We introduce MooER (摩耳): an LLM-based speech recognition and translation model developed by Moore Threads. With the MooER framework, you can transcribe the speech into text (speech recognition or, ASR), and translate it into other languages (speech translation or, AST) in a end-to-end manner. The performance of MooER is demonstrated in the subsequent section, along with our insights into model configurations, training strategies, and more, provided in our technical report.

🥊 Evaluation Results

We demonstrate the training data and the evaluation results below. For more comprehensive information, please refer to our report.

Training data

We utilize 5k hours of data (MT5K) to train our basic MooER-5K model. The data sources include:

Note that, data from the open-source datasets were randomly selected from the full training set. The in-house data, collected internally without text, were transcribed using a third-party ASR service.

Since all the above datasets were originally designed only for the speech recognition task, no translation results are available. To train our speech translation model, we used a third-party translation service to generate pseudo-labels. No data filtering techniques were applied.

At this moment, we are also developing a new model trained with 80K hours of data.

Speech Recognition

The performance of speech recognition is evaluated using WER/CER.
